Over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. The tide measures 6.3 ft at midnight, rises to a high of 12.4 ft, falls to a low of 0.2 it, and then
rises to 6.3 ft by the next midnight.
What is the equation for the sine function?

Is the orthocenter of a triangle on the inside ?

The sum of two numbers is 58. the first number is 8 less than half the second number. let  c  represent the first number. let  drepresent the second number. which statements about solving for the two numbers are true? check all that apply.the equation    represents the sum of the two numbers.the equation    represents the sentence “the first number is 8 less than half the second number.”the equation    represents the relationship between the two numbers.the equation    represents the sum of the two numbers.the number  d  is 14.the number  c  is 44.the number  c  is 14.the number  d  is 44.
